Flow for Solar Panels and Plugwise Stretch?
Eilandgast
Member
My Solarpanels (2 strings of 9 panels) with Growatt inverter are
connected to Plugwise stretch. In the Athom Pugwise-App the 2 strings turn up
fine. But I've no idea what the Flow should look like to measure the
Solar Energy. Please advise.

There is not one "the plugwise app", which one do you mean?
https://apps.athom.com/search?query=plugwise
Also: what panels, what converter, what kind of meter do you have, all depends on that... I read my energy-production with the P1 app and it's really straightforward...

And I use this Plugwise app: https://apps.athom.com/app/com.plugwise (its the only one that works with my Stretch)
And of course I did try to fix it myself, and guess: I didn't
I will be glad to get some helpful hints still. Anybody? In a PM perhaps?
What hardware did you use, a stealth or a circle? You say the strings show up fine, in assume you have two converters? 18 panels on one Circle/Stretch could become dangerous. I have 12 panels and generate about 2400 W at top moments. 3600 W is over 16A while the plugs and stretch can't handle more then 16A... Also, I blame Plugwise for that (seeing this), I was told using a circle to measure the output wasn't allowed, all wires had to be fixed.
From a usage POV:
And what do you mean by measuring Solar Energy? There's a level reported? And you can make a flow "when Energy < 3000 W" or something like this, what do you want to do? And that level is logged in insights I presume. There's a bug in Insights BTW (bug 1258), when using the block diagram the steps are made directly after the last measurement. This is the Energy-usage of one of my plugs:
From a software POV:
What is reported in the app? An Energy-level? Or total energy produced? Could you post a screenshot of the device-card in the apps-page?
I will make some further study of my solar system. In principle the Growatt 4400 TL inverter does all the measuring and counting and communicates its data to the Plugwise Stretch wireless. Next the Stretch sents its data wireless to my home network, the Plugwise apps on my Android mobile, iPad and my wired PC. From a hardware POV, in my setting, there is no danger and no relation between the Number of solarpanels and the Plugwise Stretch. When i'm home I will make some screenshots of Homeys behavior.
